Oil Change Rant..Interval and Oil.

[Beck]

Everything I own gets Mobil 1 Extended Performance and Wix filters. That version of Mobil 1 was talked about here in use in some ones drag car. I picked up on it then and haven't deviated. It used to be when you had 100k miles on a car it was worn out. Now it seems to be nothing. I rarely keep one past 120k miles. I've had no motor issues since my first new car, a 1973 Vega. Enough said on that one.
